Abstract

In the present study, monthly (except snow covered months) zooplankton variations of Lake Hafik (Sivas, Turkey), and their interaction with the environmental conditions were studied for the first time.  Lake Hafik is a mesotrophic lake based on its limnological variables. A total of 19 zooplankton species (10 crustaceans, 9 rotifers) were recorded, and  Crustaceans were  being dominant (86 % of total zooplankton abundance). Main abundant taxa (N % >5 of total zooplankton) were copepod nauplii, Arctodiaptomus bacillifer (Koelbel, 1885), Keratella quadrata (Müller, 1786), and Daphnia (Daphnia) cucullata Sars, 1862, respectively. High density and biomass of zooplankton were determined in May. In terms of diversity, lake Hafik was not rich. Statistically, rotifer density and biomass affected mainly by physical variables (temperature, DO, pH), whereas crustaceans related with nutrients and EC primarily.
